Staff rota and site inspection app for a janitorial contractor in London (2026)

The verdict in three sentences

For a cleaning contractor with 400 or more operatives, paper and spreadsheets cost more than software: unrecorded hours, cover arranged by text at 5 am and site inspections the client never sees. An off-the-shelf rota app at £3 to £6 per operative per month is enough if your contracts are standard; once you run complex site specifications, TUPE transfers and client-branded reporting, a custom build (£60,000 to £110,000, 2026 ballpark) pays back in 12 to 24 months. The real test is payroll accuracy and proof of service sent to the client, not the licence fee.

Where a paper-run cleaning business really leaks money

Take a typical London contractor: 420 operatives, around 80% part-time, 260 client sites across the City, Canary Wharf, Croydon and Park Royal. Rotas sit in one spreadsheet per area supervisor, cover is arranged by WhatsApp before dawn and timesheets come back at month end, often incomplete.

An audit usually finds the same three leaks:

• Pay rate errors: many office clients require the London Living Wage (£14.80 an hour for 2025-26), others pay the National Living Wage, and night or weekend premiums vary by contract. Mixing them on spreadsheets creates underpayments and grievances.
• Holiday pay for irregular hours is miscalculated, especially the 12.07% accrual method for part-year and irregular-hours workers.
• Missed visits still invoiced: an operative off sick, no cover sent, the client spots it and asks for a credit note worth 2 to 4% of the site's revenue.

On top of that, contract handovers under TUPE require accurate employee liability information at least 28 days before transfer. Without a digital file per operative, compiling it takes days.

Off-the-shelf app or custom build: the 2026 comparison

Workforce management vendors serving the cleaning and facilities sector usually charge £3 to £6 per operative per month, plus onboarding fees (often £2,500 to £8,000) and sometimes NFC tags or site devices. For 420 operatives that is roughly £15,000 to £30,000 a year in licences.

A custom build, quoted by an agency or a vertical software studio, sits at a 2026 ballpark of £60,000 to £110,000 for a full scope, delivered in about 5 months, followed by monthly maintenance.

The sensible path is to pilot an off-the-shelf app on one area of 40 operatives for two months. If supervisors spend more time working around the tool than using it, custom is justified.

The modules a cleaning contractor actually needs

A serious tool for a business this size covers six building blocks:

• Staff rota by site with a weekly view, absence handling and automatic suggestions of available, trained cover operatives nearby.
• Site clock-in through the mobile app, with a QR code in the cleaners' cupboard and a geofence check on arrival and departure.
• Hours and pay: contracted hours, extra hours, premiums, LLW flags, export to payroll (Sage, BrightPay or Xero).
• Site inspections with scored checklists, time-stamped photos and corrective actions, shared with the client through a portal.
• Operative file: contract, right-to-work checks, training records, data ready for TUPE.
• Dashboard: attendance rate, hours per site, margin per contract, sites on quality alert.

This is the kind of project Kolonell delivers through its custom web applications offer. Scope, price and timeline are set in the quote after a scoping workshop.

Mini case study

Rachel, managing director of a cleaning contractor in London (420 operatives, 260 sites, £15 million turnover), is choosing between a vendor at £5 per operative per month and a custom build quoted at £90,000.

• Off-the-shelf licence: 420 × £5 × 12 months = £25,200 a year, plus £6,000 onboarding.
• Custom build: £90,000, plus about £15,000 a year in maintenance and hosting.
• Gains measured on the pilot: 1.5 office FTE saved (£50,000), credit notes cut from 3% to 1% on the 30% of contracts concerned, about £90,000.

With the off-the-shelf app, only half of the credit note gain materialises because there is no branded client portal: net annual gain of about £50,000 + £45,000 - £25,200 = £69,800. With the custom build: £50,000 + £90,000 - £15,000 = £125,000 a year, paying back the £90,000 in roughly 9 months. Even halving the gains for prudence, payback stays around 20 months.

FAQ

How much does rota software for a cleaning company cost in 2026?

Off-the-shelf apps typically cost £3 to £6 per operative per month, plus £2,500 to £8,000 of onboarding. A custom build sits around £60,000 to £110,000 depending on scope, as a 2026 ballpark.

Is GPS clock-in lawful for cleaning operatives in the UK?

Yes, if it is proportionate: location checked only at clock-in and clock-out, staff informed in advance and the processing covered by a UK GDPR legitimate interest assessment. A QR code per site avoids continuous tracking and is easier to justify to the ICO.

Can the software prepare TUPE employee liability information?

Yes, if each operative has a digital file with start date, pay, hours and site history. The pack then takes minutes rather than 3 to 5 days, well within the 28-day legal deadline.

How long does rollout take for 420 operatives?

Allow about 5 months for a custom build, then 4 to 6 weeks of rollout in waves of 50 to 80 operatives. Training an operative on the clock-in app takes under 20 minutes.

Can clients see site inspections?

Yes, through a client portal showing clocked visits, inspection scores and photos. Contractors who open one often see complaints drop within the first quarter.
